Being as the pivot of avionics system, Flight Management System (FMS) plays an important role in flight planning, trajectory prediction, navigation and guidance of aircrafts. Aiming at researching the functions and validations of FMS, the advanced FMS simulation is constructed. Performance Based Navigation (PBN) and Trajectory Based Operation (TBO) require high-fidelity and high-accuracy data, of...
This paper presents a new data-driven air traffic modelling and analysis technique that can support operational risk analysis for unmanned aircraft integration. The proposed technique exploits advances in computer vision to autonomously extract and analyse the spatial distribution of arbitrary traffic densities, which can provide the foundation for quantitative and tailored risk assessments. The framework...
Safe integration of Unmanned Aircraft Systems (UAS) into the National Airspace (NAS) will require the development and fielding of a sense-and avoid (SAA) capability to augment the traditional “see-and-avoid” regulations of manned aircraft. In this paper, we focus on the problem of correctly predicting an intruder trajectory. Approaches to intruder prediction are typically grouped into three categories:...
Aviation Meteorology plays an essential role for the Air Traffic Management (ATM) automation. The availability of accurate estimates of atmosphere properties would largely increase safety and efficiency of air traffic operations. The work presented here looks forward to a net-centric serviceoriented ATM system architecture where available data, airground connectivity and modern computational resources...
To enable arriving aircraft to fly optimized descents computed by the flight management system (FMS) in congested airspace, ground automation must accurately predict descent trajectories. To support development of the predictor and its uncertainty models, descents from cruise to the meter fix were executed in a B737-700 simulator with a commercial FMS using vertical navigation. The FMS computed the...
To simulate synthetic aperture radar (SAR) raw data of extended scenes in the presence of arbitrary trajectory deviations, an efficient simulation scheme based on parallel computation in hybrid domain is proposed. We firstly present a novel target-to-antenna distance model which takes the three-dimensional components of the trajectory deviations into consideration. Then a general and compact hybrid...
Performance assessment of military wireless network designs should ideally be evaluated by replicating the conditions in which these systems will operate. For airborne networks, where network platforms are fast movers operating under noisy and unstable links environments, the representation of these environments becomes essential for network simulation modeling. However, not all simulations developed...
